Morphological characteristics of solid bamboo
The stem is 3-20cm long and 7-20mm thick. Internode length 1- 10 mm, rod height 2-3 (4.5) meters, thickness 6- 12 mm, and the number of nodes 2 1-36, slightly zigzag; Internodes are generally 12- 15 (20) cm long, the number of basal internodes is 3-7 cm long, hairless, white or sparse when young, with inconspicuous longitudinal ribs, solid or nearly solid, and the pith is sawdust-like; Folding is improved.
The rod ring is raised, even significantly raised, and it is often purple when it is young; The length of the joint is 1-3mm. The stem bud consists of 5- 1 1 piece, which is semicircular and attached to the stem. The surface is slightly rough, and there are short white fiber hairs on the edge. There are 5- 17 branches clustered on each pole, and the branches are obliquely elongated, with a diameter of only 1- 1.5 mm. When they are young, they often have white powder, and generally no secondary branches are separated. Bamboo shoots are purplish red with tawny bristles.
The sheath falls early and falls late, thin and leathery, gradually thinning towards the top, like the Yangtze River Delta, gradually narrowing at the tip, extremely sparse yellowish brown bristles on the back, with obvious longitudinal edges, small transverse veins on the upper part of the sheath are not obvious or obvious, and the edge is usually cilia-free; Ear folds and scabbard mouth? Less hair; Ligule protruding, tongue-shaped protrusion, height1-3mm; Hairless, often with small cracks at the edge.
Ligule linear-lanceolate, everted, 2-8 cm long, 1- 1.5 mm wide, base not narrowed inward, glabrous, branchlets with 3-5 leaves; Leaf sheaths are 2-3 cm long, and usually have yellow-brown short fiber hairs only at the edges; No leaf ear, no scabbard mouth? Hair or occasionally 1-2? Hair; Ligule truncated or arched, hairless, height1-1.5mm; Petiole length 1-2 mm.
Leaf blade narrowly lanceolate, (5) 7-13cm long and 5-12mm wide, with wedge-shaped base, grayish green lower surface, 3-4 pairs of secondary veins, inconspicuous small transverse veins, small serrations on one side of leaf margin and nearly smooth on the other. Flowers are missing. The bamboo shoot period is from July to September.
